A central page in Le Monde of this week (May 08), about the conundrum of dealing with the dozens of thousands of handwritten pages left by Alexandre Grothendiek, from trying to make sense of the contents to assessing the monetary value (!) of such documents. Mentioning that the most reasonable solution would be to extend the numerisation of earlier documents supervised by Jean-Michel Marin. Given the difficulty in reading these pages, as suggested by Le Monde, training an AI to translate them into regular text would make sense, if not helping with evaluating their importance…

ERC panel [step #2]

Another post that was written ages ago, about the second round of the European Research Council (ERC) panel on starting grants for mathematics in which I took part as an expert and not as an applicant. While anonymity possibly fell apart for the several dozens of applicants who were shortlisted for interview, in particular more like those few from my own field, the official list of the panel only came out much later. The interviews were quite interesting, obviously, with a strict attention to time and questions to make all interviews as “equal” as possible. And sometimes painful to attend as the candidates were visibly stressed and more over-prepared than not. Which did not necessarily help as the preparation, presumably with the help of local consultants out of maths, had removed some of the enthusiasm behind the project and too much of the maths. I think we all stopped breathing when one applicant broke mid-sentence, as in a theatre play when one actor forgets one’s lines… The rehearsal does not work so well for later questions, even though preparing for these is also essential,  and some upgrading or downgrading may then occur because of a single answer. An unavoidable limitation of the exercise.

Overall I remain impressed by the quality of the collective work of the panel [despite a gruelling schedule on interview days] and of the overall selection of eleven projects, even though it sounds like more theoretical and abstract topics seem privileged, in a bias that seems difficult to counteract. And [not because no statistics proposal was selected this time] making me (and others) wonder whether or not a separate statistics section of the ERC would not be more appropriate, since statistics proposals are not uniquely and solely centred on the maths aspects.

ERC panel [step #1]

Although this post was written ages ago, regulations of the European Research Council (ERC) prevented me from posting it until now, for confidentiality reasons. I was indeed nominated as an expert member of the ERC panel on starting grants for mathematics [a denomination including statistics, obviously, but also quantum physics or some aspects of it], which means evaluating a hundred-ish applications of young researchers (five years from PhD) to select about ten of them to be richly funded for the coming five years. The reason for secrecy is that the panel members have to be protected from pursuits from the candidates (or, more likely, from their senior mentors). While this is a pretty heavy commitment, above 20 days total, the evaluation process gets quite interesting and the most annoying part is to have to reject proposals that should be funded, were more funds available. (For obvious reasons, I cannot get into the details of individual proposals, but let me just bemoan that there were too few proposals connected to statistics!) I may however get into my appreciation of the collective work of the panel during the first step selection process. I actually knew no other member prior to my joining the panel and was impressed at how smoothly we managed to work together and incorporate different opinions in a joint perspective. When I re-read these sentences, it feels like langue de bois (double talk), really!, but they truly represent my feelings at the end of the meeting. Making me (almost) looking forward the second step of interviewing the selected candidates in another week-long meeting, again in Brussels, for the interviews and final selection and ranking. (Which is when anonymity falls apart.)

Imperial postdoc in Bayesian nonparametrics

Posted in pictures, R with tags , , , , , , , , on April 27, 2018 by xi'an

Here is another announcement for a post-doctoral position in London (UK) to work with Sarah Filippi. In the Department of Mathematics at Imperial College London. (More details on the site or in this document. Hopefully, the salary is sufficient for staying in London, if not in South Kensington!)

The post holder will work on developing a novel Bayesian Non-Parametric Test for Conditional Independence. This is at the core of modern causal discovery, itself of paramount importance throughout the sciences and in Machine Learning. As part of this project, the post holder will derive a Bayesian non-parametric testing procedure for conditional independence, scalable to high-dimensional conditioning variable. To ensure maximum impact and allow experimenters in different fields to easily apply this new methodology, the post holder will then create an open-source software package available on the R statistical programming platform. Doing so, the post holder will investigate applying this approach to real-world data from our established partners who have a track record of informing national and international bodies such as Public Health England and the World Health Organisation.

20 postdoc positions in Paris!

Posted in Kids, pictures, University life with tags , , , , , , on November 22, 2017 by xi'an

The Fondation Sciences Mathématiques de Paris (FSMP) provides funding for 20 years of post-doctoral fellowships in mathematics and in computer science for the 2018-2019 academic year. (Meaning you cannot expect a position in Paris for the coming 20 years!) Appointed fellows will hold one or two-year positions in affiliated research laboratories, starting in October 2018. This program is supported by Université Paris Sciences Lettres (PSL). If you are interested in applying for one of these fellowships, please register online. Note that the deadline is December 1!
